Spent last weekend driving through the remains of a blizard picking up nurses and taking them to a hospital. Used 4 low a little and 4 high a lot. It's a 13 JK sport with the auto transmission. Just hit 3000 miles.

After last weekend I have noticed that shifting into 4 low is much more difficult than it used to be. I really have to force it where before it went in with no problems.

It also feels like it's dragging when I accelerate. I don't really know how to describe it. No extra noise or anything, but it feels like it doesn't accelerate quite as well. I barely notice it, except that I notice it. (that makes no sense in text but it does in my head)

its a Jeep, man. when you hear a new rattle or issue, just drop the top, pull the doors and crank the tunes. all good! Kidding man. I hear and feel things all the time. with that many miles, just take it to the dealer if you think there is a problem. I'd say it's just in your head and happens to me all the time.

You in gear while trying to place in 4lo? Try neutral or park... As for the dragging, is it just on acceleration? What about when you coast? I wonder if you've gotten rocks/dirt in a caliper and your brakes are dragging... Go for a drive and feel each wheel... If one is hotter than the rest, that may be a problem....
